The Man Who Wanted to be a Goat | Nature–Design Triennial - YouTube

Thomas Thwaites conducted research for over a year before setting out to live as a goat for 3 days in the Swiss Alps. He constructed an exoskeleton that adapted his biped body into that of a quadruped, and created an artificial prosthetic rumen to enable him to live on a goat’s grassy diet. He lived successfully amongst a goat herd, observing distinctions in the natural world that he had not perceived before.
